GONDENSING ATTACHMENT FOB TEA-KETTLES.

Application filed April 14, 1914.

-boiling water and aerating the same, providing in an economical manner potable distilled water whenever desired.

The drinking water found in many places is rendered unfit for use by the presence therein of foreign substances, such as clay and earth in suspension, salts of various kinds in solution, and innumerable organic bodies which cause sickness and disease to To purify such water by filtering the same is expensive and rarely, if ever, results in pure water, and

no means, so far as known, whereby water may he distilled in an economical manner,

has been devised. To fill such a want, a simple and inexpensive apparatus, hereinafter described, has been designed that can be attached to an ordinary tea kettle to condense the steam issuing from the spout thereof, and deliver the distilled water in a potable condition into a suitable receptacle for use. The simplicity of the apparatus and the case with which it may be set up for use brings it within the reach of all and provides a ready means whereby pure drinking water is made accessible to every per.

son;

The accompanying drawing is a longitudinal sectional view of the apparatus as it appears when in use; and comprises a tube 5, preferably made of aluminum as this is the most economical of the obtainable metals that are unaffected by water, steam or heat, and gives no injurious solution or bad taste to the condensed water.

- The tube 5 is sufliciently long to insure complete condensation of all steam passing thereinto, and is preferably straight for the greater part of its length, but may be of other shape. The upper or inlet end of tube 5 that fits over the spout a of a tea kettle A is curved sufficiently .to maintain Specification of Letters Patent.

Patented Sept. 26, 1916. Serial No. 831,714.

a downwarc l inclination of the apparatus when in operative position and. insures complete drainage of the tube of all water condensed therein.

Surroundin the tube 5 for a greater portion of llJS length is a second tube 7, preferably spaced a short distance from the tube 5 and sealed water-tight thereto at its upper and lo er ends by rings of solder 8. These solder rings are cast in place by first filling the space between the inner and outer tubes with sand nearly to the ends, then pouring the molten solder into the ends of the tubes, the copper tube being sweated beforehand. The sand can be worked out between the tubes after casting the rings through the inlet and outlet apertures of the tube 7 presently to be described. The

solder rings being thus sweated to the tube 7 will always remain tight. Should, however, a leak occur between a ring 8 and the tube 5, a few light blows of a hammer over the leak will close the opening. The delivery end of the tube 5 projects a short distance beyond the tube 7 and forms a shoulder 9 that supports the lower end of the apparatus upon the edge of a receptacle {3 in which the Water of'condensation colects.

outer tube 7 is a small hollow stem 10- communicating wit 1 the space between the tubes; :1 similar stem 12 is provided at the lower end of the tube 7. Connected to these stems are two flexible. tubes 13 and 14, the former supplying cold water tothe upper end of tlze space 11, and the latter carrying oil the water that has been more end of the apparat 1S upon the edge of a receptacle B which may rest upon the floor, a stool OI. any other convenient support. The tube 13 is then connected to the cold water supplyand the end of the tube 14 carried toa suitable place or discharge. lVhen the water in the kettle begins to boil, steam emerging from the spout a enters the tube 5 and passing dowr. the same is condensed Projecting from the upper end of the B, becoming more or lessaerated during itspassage. It is not necessary to proyide a Q packing at the end of the tube that fits over the spout a of the kettle; as the metal of the tube is rather soft, the end thereof may be forced over the spout of the kettle and be sufficiently tight to prevent leakage. Usually this connection will hold the entire apparatus in position but if desired the lower end may be supported as indicated in the drawing, or a pair of crossed legs 16, indicated by dotted lines, may be provided upon which the apparatus rests.

As soon as sufficient distilled Water has been obtained the apparatus is disconnected from tlie kettle, and the tube 13 fIOIIilJllQ water supply and the apparatus put away.

1. A condenser for domestic purposes, comprising a substantially. straight tube formed of aluminum and open at both ends, one, of which ends is slightly curved and adapted to detachably engageia steam orifice of a tea-kettle or a similarvessel and receive steam issuing therefrom, and. to further maintain the tube in an inclined draining position, a second tube composed of copper of less length than the first-mentioned tube and surrounding the same fin spaced-apart relation, a soft metal ring cast in each end of the outer tube and sweatod thereto and sealed tightly to the inner tube to form a closed cooling chamberaround the inner aluminum tube, said ring being formed of a relatively soft metal that will under light pressure, or light strokes of the hammer, close any leaks that may occur between a ring and one of the tubes, an inlet leading into the upper end of said cooling chamber and a drainage pipe leading from the lower end thereof, said cooling chamber being adapted to receive cool Water through said,

inlet pipe and to discharge through said drainage pipe,
